[libnetfilter_log PATCH 1/9] build: correct pkg-config dependency configuration

[Jeremy Sowden <jeremy@azazel.net>]

Put libnfnetlink and libmnl in `Requires.private`.  They both use
pkg-config (thus `Requires`, not `Libs`), and they are both required for
static builds, but do not need to be exposed otherwise (thus
`Requires.private`).
